It would be worthwhile to figure out which wait channel they were all
piled up on; you can get this from `ps'. You may want to get both the
`wchan' (the symbolic name) and the `nwchan' (the actual address
waited on)
Most likely all hundred were piled up on the same wait channel, and
then something woke it up, causing a thundering herd of processes to
run in circles trying to grab whatever it was they were waiting for...
